SDR CONSOLE + PTT out signal

Hallo Robert,

Kan dein trx diese arbeit nicht machen via Extenal Radio von Sdrconsole?

Can your trx dont do the job via the External Radio?

Robert

on7kec if your TRX can contol TX RX switching via CAT command, then you can define this using the unused mode swtiches in external radio. I did this for my FT-736 see my post for that radio an my omnirig ini files.

NB oder WB Robert??

Robert,

Fur WB gibt es mehrere moglichkeiten

for WB there are several options

Google "ptt with pluto"

Greetings

Hallo Robert...

i am using console 3.0.21 with Pluto Firmware F5OEO ("beta for the brave") and PTT out via GPIO0,1 works on my Plutos ...in NB and WB- Mode - but the switch on/off delay is a bit long. (maybe 0.5-1s)

maybe anyone other can confirm

Michael, did you make any settings in SDR Console for using the GPIO0 and 1 ? Or work this basicly ?

Robert....

it works basically... no changes in settings were made in SDR Console.

Hallo,

look to this thread.
PTT over Ethernet

SDR-Console supports PTT-IN (USB to TTL Adapter) and PTT-OUT (HID kompatible USB-relay).

The USB to TTL-Adapter should contain a FT232 Chip from FTDI. A status line can be configured and used with a microfon button. It works with VOX also.
The output relay must follow the HID-Rules (Human Interface Device).

To bring the PTT-Signal to the amplifier use two POE-Adapters on each end of the Ethernet cable. There is no distance limit.

The GPIO-Port of the Pluto gives a PTT-Signal also. This requires firmware from F5OEO. Unfortunately there is a delay of about 800ms between Tx on and PTT-out at the GPIO-Port. Evariste, F5OEO told me, this can be reduced.
There is no matter for DATV. But fast SSB-Talking is much better without this delay.
That's why, I prefer the POE-Adapters.

Robert look here:

This works with my Pluto and the usb relais card. when I press PTT the relais goes on.

The relais must be in the system control as a HID device. There could be a conflict to load the driver if you have old Prolific chips as a comport. Then just delete them, install the relais board as HID and then the Prolific drivers again.

Hello,

For those who might be interested, I pass you the information on this board to be integrated directly into the pluto's case and which provides 2 independent and isolated PTT outputs of 0.5A. It exploits GP0 and GP1 commands and totally works with SDR Console and PlutoDVB from F5OEO. So no USB configuration to do.

Here some pictures of the board integrated in the PlutoSDR

Hallo Christian,

using the Plutos GPIO-Port to get a PTT-Signal means a delay of 800ms. Look at my report about PTT over Ethernet.
It is just some postings before. The POE-Adapters are very cheap and can simply be sticked between the Ethernet-Connectors.

800ms delay are not problematic for DATV but for SSB and CW.
Beside this the USB-Relays for PTT-Input and output allow a hardware switch may be integrated in a microphon. From my point of view it feels better then pushing the TX-Button with a mouse.

Hallo,

Pluto have no GPIO but only GPO.

Ethernet "transit" times should not be confused with the switching delay. The relay switches as soon as the Adalm Pluto is transmitted in a few tens of milliseconds or even less depending on the software method implemented. See details on this Wiki Analog Device steering Power Amp page.

Here's a well-known tip for those who don't like to use the mouse to turn SDRConsole in transmit : Press the F5 keyboard key.

Another possibility: a footswitch connected to the serial port of your PC. Details on https://www.sdr-radio.com/ptt
